As a Technician can I use both USB and LSB SSB on 10 meters?

Yes, you can use either USB or LSB. However, you will not make many contacts using LSB. Even though it is legal for you to do so, using LSB will draw attention from seasoned operators and you may be accused of being a non-ham since LSB is used predominantly on the Citizens Band.

You will notice that on160, 80 and 40 meters, LSB is mostly used and on the higher frequency bands, USB is used. This is a leftover from the early days of SSB when radios were designed a certain way, when SSB was in its infancy. Operating habits will not likely change in the future.

Thank you very much. I am considering a 10 m rig that has usb only and wanted to know if that would restrict my usage. john kk4dmt

Unless your finances are such that a 10m only radio is all you can afford, you might want to consider an all-band amateur rig instead. Unless and until the solar cycle improves a lot more, 10m will be an exercise in frustration. Upgrading to General and getting on the other bands will keep you interested in amateur radio.

Good luck!

Is USB the preferred sideband on 20, 15 and 10 meters?

Yes, USB is the convention on the 14MHz and higher bands.

I'm really confused: I'm sitting next to my wall chart of the ARRL Amateur Radio Bands. The 160, 80, 40 meters is not SSB at all unless SSB is part of the "Phone and Image" or the "RTTY and Data" category. The only band that has a Yellow section (SSB phone) is the 10 meter band. How is it that it is OK to use the 160,80,40 bands for SSB.

Sorry I misread the chart. Skipped over the 5 bands specifically set up for USB according to the ARRL: check it out hear. Some interesting restrictions:
The FCC has granted hams secondary access on USB only to five discrete 2.8-kHz-wide channels. Amateurs can not cause inference to and must accept interference from the Primary Government users. The NTIA says that hams planning to operate on 60 meters "must assure that their signal is transmitted on the channel center frequency." This means that amateurs should set their carrier frequency 1.5 kHz lower than the channel center frequency.
